HeartMate II left ventricular assist system: from concept to first clinical use
The Annals of Thoracic Surgery, 2001The HeartMate II left ventricular assist device (LVAD) (ThermoCardiosystems, Inc, Woburn, MA) has evolved from 1991 when a partnership was struck between the McGowan Center of the University of Pittsburgh and Nimbus Company. Early iterations were conceptually based on axial-flow mini-pumps (Hemopump) and began with purge bearings.

Without bystander cardiopulmonary resuscitation (CPR), cardiac arrest survival decreases 7%-10% for every minute of delay until defibrillation. Dispatcher-assisted CPR (D-CPR) has been shown to increase the rates of bystander CPR and cardiac arrest survival.

A First Approach to Hydrodynamics in General Relativistic Systems Using SPH
AIP Conference Proceedings, 2010In this work we present the Lagrangian formulation of the general relativistic ideal fluid equations. With the help of the standard Smoothed Particle Hydrodynamics (SPH) method we obtain a discretization of the motion equations. Having in mind that several of the most interesting astrophysical systems that we observe in the universe have been shaped by

Using MENTOR to teach systems thinking and OR methodology to first-year students in New Zealand
Journal of the Operational Research Society, 2000Summary: MENTOR is a multi-media, interactive, educational package, developed as separate modules by OR teachers in the United Kingdom. In 1995, we contributed a module for teaching students how to approach MS/OR projects within a framework of systems thinking.

There is a need for standardization in systemic sclerosis (SSc) management.SSc experts (n = 117) were sent 3 surveys to gain consensus for SSc management.First-line therapy for scleroderma renal crisis (SRC) was an angiotensin-converting enzyme inhibitor (ACEi). For SRC there were not many differences between treating mild or severe SRC.

THE USE OF SMALL AXIOM SYSTEMS TO TEACH REASONING TO FIRST-YEAR STUDENTS
PRIMUS, 1992ABSTRACT Small axiom systems are used to teach logic and reasoning to first year students. A collaborative technique is employed in the classroom in order to train students to write formal arguments in a non-intimidating atmosphere. Logic is considered informally rather than symbolically and is applied to small axiom systems.

Using First Nations Systems Thinking to Operationalize Sustainable Development
2015In the following chapter, a systems thinking approach is described that reflects a Canadian First Nation’s view of sustainable development. This approach is operationalized using a System Dynamics model, called Mini-World, developed by Harmut Bossel.

An exact solution to the stabilization of discrete systems using a first-order controller
IEEE Transactions on Automatic Control, 2005An exact solution is derived for stabilizing a given but arbitrary, linear time-invariant discrete system by a first-order discrete-time feedback controller, which has received considerable attention in the past few years. An approach has been recently proposed to compute the first-order controllers, given in the form of C(z)=(zx/sub 1/+x/sub 2/)/(z+x ...
